One reason that deserts tend to be found at 20 N and S latitude is that § deserts are dry. § it’s warmer near the equator. § global wind and pressure patterns affect where rain falls. § desert soils are different from tropical rain forest soils. § mountains change rainfall patterns. © 2014 Pearson Education, Inc.

From this graph, we can conclude that § each biome has distinct temperature and mean annual precipitation. § precipitation and temperature determine biomes. § precipitation determines temperature. § tundra and tropical forest are climatically different. § biomes determine precipitation. © 2014 Pearson Education, Inc.

Population ecologists are primarily interested in § understanding how biotic and abiotic factors influence the density, distribution, size, and age structure of populations. § the overall vitality of a population of organisms. § how humans affect the size of wild populations of organisms. § studying interactions among populations of organisms that inhabit the same area. § how populations evolve as natural selection acts on heritable variations among individuals and changes in gene frequency. © 2014 Pearson Education, Inc.

Dispersion patterns tend to be highly dependent on the spatial scale of the observer. For example, football players lined up on the scrimmage line are clumped at the scale of 100 yards but uniformly dispersed at the scale of a meter. An example of animals that are likely to be clumped at a large scale but uniformly distributed at a small scale is § buffalo grazing on a prairie. § bluegills swimming in a northern lake. § ant nests in an abandoned field. § red-winged blackbirds in a cattail marsh. § all of the above. © 2014 Pearson Education, Inc.

Imagine that a species of fish used to be a broadcast spawner (producing many eggs that then get no subsequent parental care) but has evolved to be a mouth brooder (holding the eggs in the parent’s mouth until they hatch and then caring for the young for a while). We would expect the survivorship curve of this species to § shift from Type I to Type II or III. § shift from Type II to Type I. § shift from Type III to Type I or II. § shift from Type II to Type III. § vary unpredictably. © 2014 Pearson Education, Inc.

The exponential growth model describes the increase in population size of a population that is not constrained by resources or space. The graph shows the elephant population in Kruger National Park, which appears to have been reproducing exponentially from 1900 to 1963. From this graph, you can tell that § none of the elephants died. § a female elephant living around 1960 was more likely to have a baby than a female elephant living around 1920. § the elephants adapted to the new park conditions around 1955. § the vegetation the elephants eat could supports more than 5, 000 elephants. § the more elephants there are, the more tourists will visit the park. © 2014 Pearson Education, Inc.

You do a study on elephants and find that there are eight elephants per acre. This is a measurement of § density. § dispersal. § demographics. § survivorship. © 2014 Pearson Education, Inc.

A population of deer grows from 100 to 200 to 600, and when it gets to 600, it levels off. This population must have reached § exponential growth. § carrying capacity. § logistic growth. © 2014 Pearson Education, Inc.
